Studies on Construction, Standerdization And Working of Microbial Fuel Cells (Mfcs) For Bioenergy Production

Microbial fuel cell (MFC) is the bioelectrochemicaldevice that utilizemicroorganismsas catalysts which convert chemical energy into electrical energy by providing a sustainable and eco-friendly source of bioenergy alternatively treating wastewater. A double chambered MFC has been constructed with salt bridge as a mean of proton transfer. The salt bridge isalso helpful in separating the two chambers. The standardizationof MFC designed was carried out by using synthetic wastewater before using the same MFC for sample analysis. The working of MFC was checked to analyze electrical potential using four different waste water samples namelyMunicipal sewage  water, Agro waste water, Dairy waste water and Distillery waste water using four different sets.The maximum potential development was 700 mV,with mediator less MFC  and potassium ferricynide as efficient catholyte with dairy waste water as substrate.
